How to use the openpgp.HKP function in openpgp

import * as openpgp from 'openpgp'

openpgp.config.aead_protect = false
openpgp.config.prefer_hash_algorithm = 2 // SHA1
var hkp = new openpgp.HKP('https://pgp.mit.edu')
var hkp2 = new openpgp.HKP('http://keys.gnupg.net')
var keyring = new openpgp.Keyring()

// Print a key
function printKey () {
  const keyid = printKeyid(this.primaryKey.getKeyId())
  const userid = printUser(this.getPrimaryUser().user)
  return keyid + ' ' + userid
}
// openpgp.key.toString = printKey

function printKeyid (keyid) {
  return keyid.toHex()
}
// openpgp.Keyid.prototype.toString = openpgp.Keyid.prototype.toHex

function printUser (user) {
